Book Chapter 1999

Autor: Freibauer, A. Westerhof, R Ayarza, Miguel Angel Silva, J.E. da Zech, W.

Short-term changes in soil aggregation, total and particulate organic C and N were studied in cropping and pasture systems of the Brazilian savannas, also known as the Cerrados. Furthermore, the concepts of a hierarchical aggregate structure and of the interaction of soil structure with particula...

Soil organic matter quality is usually seen as a major attribute of soil quality. In this study, we extracted organic carbon with water (WEOC) or with potassium permanganate (PEOC). We assessed these extractions for their potential as sensitive indicators of the effect of land use on two importan...

Little is known about the sustainability of cultivation systems in the Brazilian savannas, also known as the Cerrados, despite its increasing significance for that country`s agriculture. To characterize management effects and follow alterations of organic compounds in different fractions, we stud...

Fourteen types of physical structures produced on the soil surface by ecological engineers were sampled in the Eastern Plains of Colombia. The invertebrates creating these structures were identified. Some physical (aggregate size and stability, and bulk density) and chemical (C, N, and P contents...

Inclusion of trees in cropping systems is an efficient way to recycle nutrients and replenish soil organic matter. In the tropics, P deficiency is commonplace, and rains are erratic in many areas. Mycorrhizal fungi are known to enhance P uptake of the host-plant in low-P soils, and to improve its...

Belowground (BG) plant resource allocation, including roots and rhizodeposition, is a major source of soil organic matter. Knowledge on the amounts and turnover of BG carbon (C), nitrogen (N), and phosphorus (P) in soil is critical to the understanding of how these elements cycle in soil-plant sy...
